Abstract

This paper has demonstrated a robust and simple technique to spatially resolve light emission from a vertical cavity surface emitting laser (VCSEL). The technique allows the mode structure, carrier density, and net cavity loss to be mapped. The measurements allow ready assessment of optical guiding in the structure. It is found that in larger area devices with low ohmic heating the guiding is dominated by free carrier effects.
